Claudia Winkleman has named her newborn son Arthur.
The 'King Of...' host - who also has two children, Jake, eight, and five-year-old Matilda, with husband Kris Thykier - joked that she was happy to find she wasn't becoming a mother to a "goat" as her scans had suggested, but a little boy with "extraordinary eyebrows".
Writing on her twitter page, she said: "Well, it turns out I wasn't making a goat. We have a beautiful baby boy. He has twinkly eyes and extraordinary eyebrows. His name is Arthur. (sic)"
However, Claudia admitted she will be giving the tot a cute nickname.
She added: "I think I will be calling him Art or Pumpkin. Or Rabbit. (sic)"
The 39-year-old presenter recently quit fronting 'Strictly Come Dancing' spin-off 'It Takes Two' in favour of "watching from the sofa" with her new arrival.
Claudia said: "No more 'It Takes Two', I can't believe it. I will miss it so much. Everyone who watches 'Strictly' knows how much I love the show and enjoy presenting 'It Takes Two'.
"This year I'm dipping out, but can't wait to watch it from the sofa."
